Vista Remote Connection Problem - Login Failed For User 'xxxxxxx. (.Net SqlClient Data Provider)

May 26, 2007

trying to connect to sql server 2005 over the internet. (its a third paty hosting company i'm using)

so i have to connect via tcp/ip using sql server authentication.

my laptop is running vista.



the version of sql server 2005 on my laptopis developer edition with service pack 2.

it worked fine from windows xp and the connection details are valid as it runa fine from .net on the hosting website.



i have added sql serer managemnt studio to the exceptions list in the firewall.

ihave made sure tcpip is enabled in the sql server connection management console.

i have also enabled it in the cliconfg tool



firewall on/off seems to make no difference.



its almost enough to make you turn to oracle and thats saying something considering how long i've been in the microsoft camp...



the error returned is:
Login failed for user 'SQL2005_152092_garethbowen'. (.Net SqlClient Data Provider)

System.Data.SqlClient.SqlException: Login Failed For User 'ext_access'

May 2, 2008

I am having a very strange and frustrating problem with moving an application from Development to Production.
I have been working on this application on XP with VS2005 with SQL Express on my local machine.  Throughout the development lifecycle I have moved it to the Server multiple times to test things and everything has been working fine until this last time.
What I have done since the last time:
Added some ASP.NET AJAX functionality
Added some views that I am having to fill a dataset from the dataset to manipulate the data before presentation.
Everything has worked fine without any issues on my local machine with my local database.
I just made backups of the databases and restored them on the server and have moved all my project files up to the server.  I then installed the ASP.NET AJAX Extensions 1.0 on my 2.0 server.
 
NOW - The Problem:
The entire site works fine, I can read data from every table of every database, and I can also write data to all the databases.  However, this one page has a GridView that I pull data from the database and fill a DataSet with the data.  I then manipulate the data, adding some data from other databases and then present it to the browser.
This is working fine on my local machine, but since pushing this to the server I get an error:
System.Data.SqlClient.SqlException: Login failed for user 'ext_access'
Line 36:         ad.Fill(ds, "CaskInfo")Line 37:         Dim Table As DataTable = ds.Tables("CaskInfo")Line 38:         Table.Columns.Add("Company", GetType(String))
I have checked the database and the SQL Server and the user listed above has the correct access to the database, which I would guess since everthing else is working fine. I use the same connection information throughout the app and it is stored in the web.config so I am certain nothing is wrong with my connection information.  I access that information with the same code throughout the application as well so I know it is correct.
I know this may not be the most trimmed piece of SQL code, but I figured I would post it incase there is something inefficient in my SQL that could be causing this.
Here is my code leading up to the error.
Dim conn As SqlConnection = CreateConnection2()Dim connectionString As String = conn.ConnectionString
Dim myConnection As New SqlConnection(connectionString)Dim ad As New SqlDataAdapter("Select CaskID, CompanyID, SiteID, UnitIDVCC, UnitIDTSC, DATEPART(mm,DateLoaded)as Month, DATEPART(dd,DateLoaded)as Day, DATEPART(yyyy,DateLoaded)as Year, COCName, AmendmentName, HeatLoad, Dose, DryTime, Damaged, Debris FROM CaskInfo, COCInfo, AmendmentInfo WHERE CaskInfo.COC = COCInfo.COCID AND CaskInfo.Amendment = AmendmentInfo.AmendmentID", myConnection)
Dim ds As New DataSet()
ad.Fill(ds, "CaskInfo")
 
 
Using this connection code:Function CreateConnection2() As SqlConnection
Dim conn2 As SqlConnection = New SqlConnectionconn2.ConnectionString = ConfigurationManager.ConnectionStrings("MainWeb").ConnectionString
conn2.Open()Return conn2
End Function
And this is the line in the web.config:
<add name="MainWeb" connectionString="Data Source=N2K3APPS;Initial Catalog=NUTUGData;Integrated Security=false;Pooling=False;User Id=ext_access;password=zzzzzzz" providerName=".NET Framework Data Provider for SQL Server"/>
Thanks!

System.Data.SqlClient.SqlException: Login Failed For User 'NT AUTHORITYANONYMOUS LOG

Apr 2, 2004

I have searched all the forums on this issue and tried the other options but nothing seems to work. I have an IIS server using asp.net to connect to a SQL database on a separate server which also happens to be a domain controller(i.e. no local accounts). I have tried changing the connection string, web.config, etc. but I still can't get connected. I believe the issue is with the SQL security but I'm not sure.

IIs is set up for Integrated Windows Auth.

Here is the web.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<!-- application specific settings -->
<appSettings>
<add key="connectionString" value="Data Source=VGISQL2;Initial Catalog=PaymentApplication;Integrated Security=SSPI;" />
</appSettings>


<system.web>

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<compilation
defaultLanguage="c#"
debug="true"
/>

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.

"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customErrors
mode="Off"
/>

<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"

"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<authentication mode="Windows" />

<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->

<authorization>
<allow users="*" /> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>

<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.
-->
<trace
enabled="true"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"

<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests belong to a particular session.
If cookies are not available, a session can be tracked by adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionState

sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"

<!-- GLOBALIZATION
This section sets the globalization settings of the application.

SQL SERVER 2005 + ASP.NET 2.0: Problems With Data.SqlClient.SqlConnection --&> Login Failed For User 'username'

Apr 23, 2007

I have lots of problems with the connection. I've connected many dropdownlists to the database and i didn't have problems at all. I also try an example of an ASP.NET book:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString= "<%$ ConnectionStrings:CIPPEC%>"
InsertCommand=
"INSERT INTO
[member] ([first_name], [last_name], [malefemale], [yearborn])
VALUES
(@first_name, @last_name, @malefemale, @yearborn)">
<InsertParameters>
<asp:FormParameter Name="first_name" Type="String"
FormField="FirstTextBox" />
<asp:FormParameter Name="last_name" Type="String"
FormField="LastTextbox"/>
<asp:FormParameter Name="malefemale" Type="Int32"
FormField="MFRadioButton" />
<asp:FormParameter Name="yearborn" Type="Int32"
FormField="YearDropDown" />
</InsertParameters>
</asp:SqlDataSource>
And it worked well.  But when i try to connect my page with:
Dim connect As New Data.SqlClient.SqlConnection( _
"Server=glgrand-arSQLEXPRESS;UID="WindowsStartupUser";password="WindowsStartupPass"; database=CIPPEC")
connect.Open()
Dim cmd As New Data.SqlClient.SqlCommand( _
"INSERT PRUEBA (PersonaJuridica, NombreRazonSocial, Nombre, Segundo_nombre, Apellido) " & _
"VALUES (txtPerJur, txtRazSoc, txtName, txtSecondName, txtApellido)", _
connect)
cmd.ExecuteNonQuery()
connect.Close()
The error message says: Login failed for user 'username'.
I tried lots of things but it didn't work:
In SQL Configuration Manager:
Client Protocols: TCP/IP and Named Pipes are enabled.
In SQL 2005 Services: Server Properties: Built-in Account: Local System
SQL Server Surface Area Configuration: Remote connections: Using both TCP/IP and Name Pipes connection is selected.
In SQL Management Studio i created a new login glgrand-ar/UserStartupName , with sysadmin server role and user mapping my CIPPEC database.
I don't know what else i could try, i tried it at home and at work and i couldn't connect to my database and make an INSERT. It stops at Connect.Open() with the error that i wrote in this subject message.
It's evident that i'm doing something wrong (because i'm new): Could you please help me with a solution and explain me what are the data that i have to put on the Data.SqlClient.SqlConnection ?? I'm using the Windows authentication: i'm putting my username and password and it doesn't worked.
Thank you!!

Login Failed For Trusted Connection Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'

Mar 13, 2007

We have a SQL 2000 Active/Passive cluster running on Windows 2000. On one node, everything logs in fine (second node is powered off). I can use local authentication fine in OSQL (-E) and even see my connection in SQLEM current activity as [DomainUser] for the NT account which I am logged in as. Then I bring the second node online and initiate a failover. SQL Server starts but Cluster Admin cannot connect and starts throwing this Anonymous Logon error. I open a command prompt and try the same OSQL (-E) local login and sure enough it is also giving the Anonymous Logon connection user. I do not understand why the failover to a second node is causing the Trusted Connection Local authentication to switch to Anonymous instead of the [DomainUser] which I am using. Any help is appreciated. John.

Login Failed For User 'testuser'. The User Is Not Associated With A Trusted SQL Server Connection.

Aug 19, 2006

Hi,
I have a copy of VS2005 and i have installed the Microsoft SQL Server Developer Edition
I am trying to do my first connection using ASP.net (yay for me...) and it has failed...with this error..Login failed for user 'testuser'. The user is not associated with a trusted SQL Server connection.
 
can someone please point out why? yes i know that the error seems pretty straight forward but how do i fix it? like how do i make the user a trusted server connection? where do i do it? and what are the steps? the user is an administrator and by rights should have all access to everything....
 
connection string
 
SqlConnection MySQLConnection;              MySQLConnection = new SqlConnection("server=cmptrname\databsename;uid=testuser;password=password;database=mytest");
 
btw while your reading do you have any examples of opening a db with the connection string in the web.config file? because i get some error "connection string has not been initialised"  using the
system.Configuration.ConfigurationManager.AppSettings.Get
i though i would stick to the top code first before i tackled the web config error first....
 
Thanks heaps

Error Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

All the research I found dealing with this problem is that the solution is to set SQLserver to mix mode.  I have SQL server already set to mix mode. I am not sure what else to do. Has anybody run into this problem?

[298] SQLServer Error: 18452, Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Mar 11, 2008

I received the above error yesterday and haven't been able to trace it to any job or process running. We haven't implemented any changes to the server in the past few months, and it doesn't look to be a user-established connection, since the Client IP Address of the SSPI handshake error is from the server itself.

I logged this set of messages in SQL AgentServer error log:

Any help in explaining this would be greatly appreciated.

Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Oct 23, 2006

I've seen many, many, many, many posts regarding this topic - but none have been able to fully explain nor fix my problem.I've developed a security solution according to Scott Gu's guide and it works great - but only on my local machine running VWD and SQLExp2005. Once I move this application it completely breaks in the productions environment.  Today I managed to get it halfway there. I created a SQL login and changed my web.config to use these credentials - now the web application will come up, but none of my links (that are role based) are displayed - most likely because i'm authenticating as the SQL credentials instead of me. So I switch it back to windows authenticated, as it is on my laptop, and it breaks again. Please tell me theres a way to get this working in production and Scott's fantastic tutorial hasn't wasted me 2 weeks of work. Here's the exact error I get when using Integrated authentication:
Server Error in '/Contracts' Application.

Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Jan 29, 2008

Arrgh!  I've check and to make sure SQL Server and Windows Authentication option is selected.  The user has Grant access to connect to database engine and Login is enabled...and also has database read/write privs.  I can login using the username/password from Mangement Studio Express, but I can't from my app.  Here is my web.config:
<connectionStrings>    <add name="CPT_ConnectionString"          connectionString="Data Source=192.168.1.40ccsql1;Integrated Security=SSPI;"         providerName="System.Data.SqlClient" />  </connectionStrings>  <system.web>    <identity impersonate="true"></identity>  </system.web>
The only thing I can think of is that my app is using a DSN to connect to the database.  Any ideas?
Many thanks,
Mark

Login Failed For User . The User Is Not Associated With Trusted Sql Server Connection

Dec 13, 2007

We are wanting to use SQLEXPRESS in a workgroup called REALITY, no servers just PCs. I have four PCs in this workgroup and need them all to share the same database from one of the PCs. I can share folders and map a network drive but can not connect to the SQLEXPRESS database remotely.

I have set server authentication mode to Windows and SQL and have enable local and remote connections (TCP/IP only) in the surface area. After making these modifications I was able to connect to the database through the SQL Server Management Studio Express after I enable the guest account. When I first started I had numerous connection errors and have worked through them all by performing the above and was only finally able to connect after enabling the guest account and adding said account to the SecurityLogins. However, today I am unable to connect I have double and triple checked the settings and still continue to receive the same error.
